Template case files to help general setup of OpenFOAM cases

The templates include a stategy to simplify meshing with snappyHexMesh,
particularly to help generate an initial mesh quickly that can subsequently be
improved.  The templates are setup to enable rapid initial simulations, typically
with simpleFoam.  The initial templates cover simple inflow-outflow and closed
domains, including rotating geometry, and an example axisymmetric flow.  For
more details, consult the README file accompanying each template case.
The cases are located in $FOAM_ETC/templates

+Overview
+========
++ Template case for axisymmetric jet flow
++ The main purpose of this template is to demonstrate a simple, reliable meshing
+  strategy for axisymmetric flow
+
+Meshing
+=======
++ The blockMeshDict file contains a backgroundMesh subditionary
++ In backgroundMesh set the geometry radius and length and jet radius
++ Set the number of cells in the length and radial directions
++ Run blockMesh to generate a 2D "slab" mesh
++ Run extrudeMesh to convert the mesh into a 2D axisymmetric mesh with wedge
+  front and back patches
+
+Initialisation
+==============
++ In the field files in the 0 directory, set inlet values
++ For example, in 0/U, set the inlet velocity Uinlet
++ Set the viscosity in constant/transportProperties
+
+Output
+======
++ Graph data of field values along the centreline are written to files in
+  postProcessing/graph
